A rock is suspended from a string, and it accelerates downward. Which one of the following statements is correct? Group of answe

Tems11 [23]

Answer:

a. The magnitude of the tension in the string is greater than the magnitude of the weight of the rock.

Explanation:

During the motion of the rock while it is in downward motion we can say

$T - mg cos\theta = ma_c$

since it is performing circular motion so we will have its acceleration towards its center

$T = mgcos\theta + ma_c$

$a_c = \frac{v^2}{L}$

$T = mgcos\theta + \frac{mv^2}{L}$

So at the lowest point of the path we can say

$T = mg + \frac{mv^2}{L}$

so correct answer is

a. The magnitude of the tension in the string is greater than the magnitude of the weight of the rock.
